# Copy this code to play with. nums = list(range(3, 15, 3)) print(nums) # shows the list print() #`list slicing starts from 0 print(nums[0]) print(nums[1]) print(nums[2]) print(nums[3])

Let me translate this to English. line 1 says :- Iterate from 3 to 15 in steps of 3 and put every number in a list named *nums* So after first line, "nums" will look something like this {3,6,9,12} Now second line says that take the value at index == 2 of nums and print it's value, which turns out to be 9 as list index starts from 0 and not 1. So the final output would be 9.

The answer is 9: Since the list of numbers in num were 3, 15, and 3, the last number 3 is the skip count of the range between 3 and 15 When nums is printed out from the [2] thing, it resulted printing out 9: Visualization: 0 = 3 1 = 6 2 = (9) Note it that the last number is covered with parentheses. Remember, counting arrays start from 0

nums is a list which will look like this: [ 3, 6, 9, 12] list slicing -> nums[2] will give a result of 9 I will try to find the python lessons pertaining to this and post them here for you to review
